A House committee has launched an investigation into whether EPA Administrator Lisa Jackson used an email alias to try to hide correspondence from open-government requests and her agencyâs own internal watchdog â something that Republican lawmakers said could run afoul of the law.

The science committee has asked Ms. Jackson to turn over all information related to an email account under the name of âRichard Windsor,â which is one of the aliases identified by a researcher looking into the EPA.

The committee has also asked the White Houseâs lawyer and EPAâs inspector general to look into the matter and report back by the end of this month, saying that the secret email accounts could have been used to keep key information from official watchdogs as well as the public.

âYou remember Ms. Browner, the lady who suddenly ordered her computer hard drive reformatted and backup tapes erased, hours after a federal court issued a âpreserveâ order â¦ that her lawyers at the Clinton Justice Department insisted they hadnât yet told her about?â Horner told TheDC News Foundation. âThe one who said itâs all good because she didnât use her computer for email anyway? That one?
